EF460-500 Electronic Overload Relay
Manufacturer: ABB
Product ID: 1SAX721001R1101
EAN: 4013614487415
The EF460-500 is a self-supplied electronic overload relay, which means no extra external supply is needed. It offers reliable and fast protection for motors in the event of overload or phase failure. Easy to use like a thermal overload relay and compatible with standard motor applications, the electronic overload relay is convincing, above all, due to its wide setting range from 150 to 500 A, high accuracy, high operational temperature range, and the possibility to select a trip class (10E, 20E, 30E). Features include temperature compensation, trip contact (NC), signal contact (NO), automatic or manual reset selectable, trip-free mechanism, STOP and Test function as well as trip indication. EF460 has ATEX and IECEx certification. ATEX is valid for products produced from week 42, 2014. IECEx is valid for products produced from week 15, 2017.
